Do you have the required access to create replication
policies?
Power users, the user who onboarded the
source and target clusters, and users with
ClassicClusterAdmin or
ClassicClusterUser resource
roles can create replication polices on clusters for
which they have access.
Do you have the required access to view the replication
policies?
HDFS replication policies - The existing
policies are visible to users who have access to
the source cluster in the policy.
Hive and HBase replication policies - The
existing policies are visible to Replication
Manager users if they have access to the
destination cluster in the policy. A warning
appears if they do not have access to the source
cluster.
If you can view the policies, you can
perform other actions on the policy which includes
policy update and policy delete
operations.
To replicate data securely
Have you configured an SSL/TLS certificate exchange between two
Cloudera Manager instances that manage source and target clusters
respectively?
Do the source cluster and target cluster meet the
requirements specified in the Support
Matrix?
Is the source on-premises cluster registered as a classic
cluster?
Do you have the required cluster access to create or view
replication policies?
Do you have the required cloud credentials to access and
use AWS or ADLS (target cluster)?
Is an external account available in the Cloudera Manager
instance that has access to the bucket or container
where the HDFS data is being copied to?
Have you configured an SSL/TLS certificate exchange
between two Cloudera Manager instances that manage
source and target clusters respectively to replicate
data securely?
To create Hive replication policies
Do the source cluster and target cluster meet the
requirements specified in the Support
Matrix?
Is the source on-premises cluster registered as a classic
cluster?
Do you have the required cloud credentials to access and
use AWS or ADLS (target cluster)?
Do you have the required cluster access to create or view
replication policies?
Is an external account configured on the source CDH
cluster's Cloudera Manager that allows the CDH cluster
to access CDP cloud storage?
Have you configured an SSL/TLS certificate exchange
between two Cloudera Manager instances that manage
source and target clusters respectively to replicate
data securely?
To create HBase replication policies
Do the source cluster and target cluster meet the
requirements specified in the Support
Matrix?
Is the source on-premises cluster registered as a classic
cluster?
Are the following steps complete on the CDP Private Cloud
Base source cluster or CDH source cluster (these steps
are not required for COD sources)?
Have you installed the HBase
replication plugin parcel in the CDH source
clusters?
Applicable for CDH versions 7.2.x that
are lower than 7.2.2, versions 7.1.x that are
lower than 7.1.5, and for versions lower than 7.x.
For more information, see Cloudera
Replication Plugin.
Have you created the
/user/hbase folder for the
hbase user in HDFS in the
source cluster?
Applicable for Cloudera Manager
versions 7.4.3 or lower.
These
commands allow the HBase replication policy to
replicate the existing data in the source
cluster.
Do you have the required cloud credentials to access and
use AWS or ADLS (target cluster)?
Have you assigned the managed identity of source roles,
Storage Blob Data Owner or
Storage Blob Data
Contributor, to the destination storage data
container and vice versa for bidirectional replication
when you are using COD on Microsoft Azure?
The roles allow writing a snapshot in the destination
cluster container.
Do you have the required cluster access to create or view
replication policies?
Is the required target cluster (Data Hub or COD)
available and healthy?
Are the required ports including ports 2181 and 16020 on
the destination hosts of the AWS cluster or ADLS cluster
(target cluster), and the Cloudera Manager server port
on the source cluster open and available?
Verify whether the ports 16020 for worker security group
and 2181 for worker, master, and leader groups are open
for connection from the source cluster to the
destination cluster on AWS or Azure. This ensures that
the source HBase service can communicate with Zookeeper
and HBase services on the destination hosts
uninterruptedly. For more information, see Ports for HBase
replication.
Does DNS resolution work as expected between the source
and destination clusters?
Have you configured an SSL/TLS certificate exchange
between two Cloudera Manager instances that manage
source and target clusters respectively to replicate
data securely?
You can also use CDP CLI commands for HDFS and Hive replication policies. The CDP CLI
commands for Replication Manager are under the replicationmanager
CDP CLI option. For more information, see CDP CLI for Replication Manager.
